FARM-GATE.

Application filed June 13, 1916.

T 0 all whom it may concern Be it known that I, WILLIAM STEPHEN HOLLAND a citizen of the United States, residing at Bedford, in the county of Bedford and State of Virginia, have invented new and useful Improvements in Farm- Gates, of which the following is a specification.

This invention relates to farm gates and it consists in'the novel features hereinafter described and claimed.

An object of the invention is to provide a gate of the character indicated which is of simple and durable structure and which includes a panel hingedly mounted upon a supporting post and having a latch member adapted to engage keepers mounted upon suitable posts. 1

An object of the invention is to provide in combination with a gate panel of the character indicated means adapted to be operated by a vehicle wheel for swinging the panel from a closed to an open position and vice versa. The gate panel is provided with two such means one located at each side of the panel and both operatively connected with the same. Each operating means includes a pivotally mounted spring actuated trip which normally lies upon the ground, a ramp forswinging the said trip from a lowered to an elevated position when the said ramp is engaged by an approaching wheel, and a second ramp adapted to move the trip into engagement with the gate operating means and also adapted to be engaged by the vehicle wheel. When the elevated trip is engaged by the vehicle wheel it moves the gate operating means whereby the panel is swung from a closed to an open position and simultaneously the other trip is swung from alowered to an elevated positi on. When the vehicle passes through the gate opening the wheel encounters the last i mentioned trip which is swung whereby the connecting means swings the gate panel from an open to a closed position.

Another object of the invention is to so arrange the elements and the features of the device as to render it practically impossible for cattle or stock to open or close the gate panel by walking or stepping on the ramps or the trips. In other words, the parts are Specification of Letters Patent.

The gate structure includes a hinged post 1 which is planted in the ground in the usual manner and upon which is mounted alined bearings 2. A shaft 3 is journaled in the bearings 2. A resilient arm 4 is attached to the shaft 3 at a point between the bearings 2 and the said arm carries at its lower end a curved shoe 5. A gate panel 6 is hingedly mounted upon the shaft 3 and carries at its free edge a spring latch 7. A wire 8 or other suitable element is connected at one end with the free end portion of the latch 7 and at its other end with one end of the shoe 5. A post 9 is planted in the ground opposite the post 1 and carries keeper 10 in which the latch 7 is adapted to engage when the panel 6 is secured in a closed position. Posts 11 are planted in the ground at the opposite sides of the hinge post 1 and carry suitable keepers 12. A gear wheel 13 is fixed to the lower inner corners of the panel '6 and receives the lower portion of the shaft 3. The said gear wheel 13 is concentermediate portion of which is transversely disposed across the upper side of the lowermost bearing 2. The yoke 15 is provided at its intermediate portion with an upstanding lug 16 which is received within the curved shoe 5 as best shown in Fig. 3 of the drawing.

When the bar 14 is moved longitudinally the yoke 15 moves with the same and the lug 16 comes in contact with the shoe 5 and by reason of the curvature of the said shoe the lowermost portion of the arm 4 is moved in a direction away from the adjacent edge of the gate panel 6 whereby the wire 8 is moved longitudinally and the upper portion of the latch 7 is moved toward the adjacent edge of the gate panel 6. Therefore the said latch 7 may be withdrawn from the keeper 10 or either of the keepers 12 with which it might be in engagement when the bar 14 is moved longitudinally. The parts are so arranged and proportioned that it makes no difference in which direction the bar 14 is moved for if the said bar is moved in either of two directions the upper end of the latch 7 is drawn toward the adjacent edge of the panel 6 and consequently the said latch is moved out of engagement with any keeper with which it might be in contact. A U- shaped rack bar 17 is slidably mounted upon the bar 14 and the said bar 17 is provided at its intermediate portion with teeth which engage the teeth of the gear wheel 13 as best shown in Figs. 4 and 3 of the drawings. A stop member 18 is fixed to the intermediate portion of the bar 14 and coil springs 19 are interposed between the said stop member 18 and the ends of the bar 17 and serve to resiliently hold the bar 17 in position upon the bar 14. Upon the initial movement of the bar 14 one of the springs 19 compresses and the other elongates whereby the bar 17 does not move with the initial movement of the bar 14. But when one of the said springs 19 is sufficiently compressed the bar 17 moves with the bar 14. Thus the initial movement of the bar 14 serves to disengage the latch 7 from that keeper in which it is in engagement and the final movement of the bar 14 serves to move the bar 17 and through the engagement between the bar 17 and the gear wheel 13 the gate panel 6 is swung with relation to the hinge post 1. Panel swinging mechanisms A and B are located at the opposite sides of the hinge post 1 and inasmuch as these mechanisms are alike a description of one will answer. Each panel swinging mechanism comprises a plate 20 and a bearing 21. A trip shaft 22 is journaled in the plate 20 and bearing 21 and the said shaft is provided at a point between the plate 20 and bearing 21 with a crank portion 23. A coil spring 24 is attached at one end to the'shaft 22 and its other end to the bearing 21 and the tension of the said spring 24 is such to normally hold the crank 23 toward the bearing 21.

crank 25 and a lug 26 is mounted upon the intermediate portion of the said crank A resilient ramp 27 is secured at a fixed po sition adjacent the bearing 21 and the said ramp is provided with an upstanding lug 28 which is adapted to engage the end of the shaft 22 and move the same longitudinally against the tension of the spring 24 when the free end portion of the said ramp 27 is depressed. A resilient ramp 29 is also securedat a fixed position and is disposed approximately parallel with the ramp 27 and spaced therefrom. A lever 30 is fulcrumed at the side of the plate 20 and one end of the said lever is connected with the free end of the ramp 29 and the other end of the said lever lies under the intermediate portion of the crank 23 0f the shaft 22.

A shaft 31 is journaled in the plate 20 and the said shaft is provided at one end with a crank 32 having at its free end an angularly disposed extremity 33. The shaft 31 is further provided with a crank end 34 to which one end of a rod 35 is pivotally connected. The inner end of the rod 35 is connected with one end of the bar 14. A lug 36 is carried by the rod 35 and is adapted to cooperate with the lug 26 upon the intermediate portion of the crank 25 and explained hereinafter. I

The operation of the gate structure is as follows :Assuming that the parts are in the positions shown in Fig. 1 which is the normal positions of the parts and a vehicle is approaching the panel operating mechanism A, Fig. 8 of thedrawing indicates the relative positions of the parts of the said panel operating mechanism. The said panel operating mechanism with the wheel of the vehicle is diagrammatically represented at 37. WVhen the wheel 37 moves upon the ramp 29 the same is depressed to the positions shown in Fig. 9 of the drawing. Thus the leier 30 is swung upon its pivotal connection with the plate 20 and its extremity 33 engages under the intermediate portion of the crank 23 of the shaft 22 and swings the said portion 23 to the inclined position shown in Fig. 9 of the drawing. At this position it will be observed that the intermediate part of the crank portion 23 is above the extremity 33 of the crank 32. The wheel 37 then moves upon and depresses the ramp 27 .whereby the same is caused to assume the position shown in Fig. 10 of the drawing. During the downward movement ofthe free end of the ramp 27 the lug 28 thereof encounters the end of the shaft 22 and moves the said shaft longitudinally against the tension of the spring 21 hereinbefore described whereby the intermediate portion of the crank 23 is carried into engagement with the extremity 33 of the crank 32. The wheel 37 then encounters the intermediate portion of the crank 23 and depresses the same to the position shown in Fig. 11 of the drawing. During the downward movement of the crank portion 23 the shaft 22 is rotated or turned whereby the lug 26 carried upon the crank 25 encounters the lug 36 and the rod 35 is moved longitudinally. Inasmuch as the said rod 35 is connected with the bar 14 the bar 14 is moved and the gate panel 6 is swung from a closed to an open position as hereinbefore described. After the wheel 37 passes beyond the ramps 29 and 27 the said ramps by reason of their resiliency swing back to the elevated positions as shown in Fig. 11 of the drawing.

Inasmuch as the rod 35 of the panel operating mechanism B is connected with the bar 14, the said rod 35 of the mechanism B is moved longitudinally whereby the crank portion 23 of the shaft 22 of the mechanism B is elevated or swung to the positions shown in Fig. 12 of the drawing. After the vehicle passes through the gate opening and the wheel 37 approaches the mechanism B the said wheel engages the elevated crank portion 23 and swings the same down to the position 'shown in Fig. 1,3. Therefore the shaft 22 of the mechanism B is turned whereby the crank extremity 25 of the shaft 22 encounters the intermediate portion of the crank 34 and the rod 35 is moved longitudinally. Inasmuch as the rod of the mechanism B is also connected with the bar 1a the said bar 14 is moved longitudinally and the gate panel is swung from an open to a closed position. From the foregoing description taken in conjunction with the accompanying drawing it will be seen that a gate structure of simple and durable nature is provided and that the same may be automatically operated by the wheel of an approaching vehicle for opening a. gate panel and closing the same after the vehicle has passed through the gate opening. By reason of the fact that the ramps are adapted to operate successively in conjunction with the crank trip of the shaft 22 it is practically impossible for animals moving or walking about the structure to accidentally open or close the same.
